The Fundamentals of HVAC Direct Digital Control—Practical Applications and Design
4th Edition, 2021 (Available Oct., 2021)
By Frank Shadpour
310 Pages, Hardcover
The book is directed towards the design of DDC systems. However, the first six chapters give a good explanation of the fundamentals of DDC without the usual technical engineering terms of computer jargon. If you have an understanding of central air handling units and of automatic control systems in general, this is a good introduction to DDC controls. You can get a good understanding of what DDC is all about. But the book focuses on the computer side of DDC systems. It touches only lightly on the mechanical aspects such as economizer cycles, deadbands, and normally open and normally closed valves.
LEO RECOMMENDS
There's a lot of good information in these chapters—the author doesn't get too deep into design technicalities. I found the section on parallel and opposed blade dampers very good. And the schematics of different hydronic systems was very informative. For a rather technical subject, the book is easy to read. There is an occasional stumbling block because of failure to define terms. However, there is a glossary. I would have liked a key to abbreviations and symbols with each schematic drawing.
